Problem with IntRect or setTextureRect
« on: October 24, 2018, 06:09:06 pm »
Hello,
So I've struggling to find if its a problem with my code or anything else on my part. (Also, tried different Visual Studio versions, different textures/sprites, also tried inside a VM and with different SFML versions 2.4/2.5.1).

I've attached the whole project.
The way its supposed to look : https://imgur.com/a/o8Wc2oZ
And how it looks : https://imgur.com/a/rzU6zM1

Also here is the code :
Code: [Select]
#include "SFML/Graphics.hpp"

int main(int argc, char ** argv) {
sf::RenderWindow renderWindow(sf::VideoMode(640, 480), "Demo Game");

sf::Event event;
sf::Texture texture;
texture.loadFromFile("images/dragonFrames.png");

sf::IntRect rectSourceSprite(300, 0, 300, 400);
sf::Sprite sprite(texture, rectSourceSprite);
sf::Clock clock;

while (renderWindow.isOpen()) {
while (renderWindow.pollEvent(event)) {
if (event.type == sf::Event::EventType::Closed)
renderWindow.close();
}

if (clock.getElapsedTime().asSeconds() > 1.0f) {
if (rectSourceSprite.left == 600)
rectSourceSprite.left = 0;
else
rectSourceSprite.left += 300;

sprite.setTextureRect(rectSourceSprite);
clock.restart();
}


renderWindow.clear();
renderWindow.draw(sprite);
renderWindow.display();
}
}

What is the width and height of dragonFrames.png? Is it only 300x400?

Ok, yeah your texture looks to be 319x424.

sf::IntRect rectSourceSprite(300, 0, 300, 400);
sf::Sprite sprite(texture, rectSourceSprite);
 

You're setting your sprite to be almost the same size as the whole texture.

The initial x position (offset of the rectangle from the left side) is causing the texture to almost entirely miss the significant part of the image.

You most likely want the IntRect to start with zero.
